Patent JP-H1165322-A (JP)
Title: Image forming device
Inventor: YODA YASUO
IPC: G03G15/01
Filed: 1997-08-26
Abstract: PROBLEM TO BE SOLVED: To prevent charging up caused by the fact that an electric charge having a polarity opposite to that of an applied transfer bias is accumulated on a transfer belt, at the time of performing a transfer. SOLUTION: At the time of performing a secondary transfer, the transfer belt 8 is abutted on the nonimage region except an image region of an intermediate transfer drum 7 as well. A controller 16 executes control for applying the transfer bias having the polarity opposite to that of the transfer bias, in the nonimage region. Further, when the peripheral length of the intermediate transfer drum 7 is defined as Li (mm), the peripheral length of the transfer belt 8 is defined as Lb (mm), a reverse polarity transfer bias applying time in the nonimage region is defined as Tr (msec) and the process speed of a photoreceptor drum 1 is defined as Vp (mm/sec), the above-mentioned values are set to satisfy Vp.Tr>(Li-n.Lb) (where (n) is an integer for satisfying Lb>=(Li-n.Lb)>0.  Thus, the surface of the transfer belt 8 can be easily destaticized to prevent a deterioration in an image due to the charging up.

Title: Battery connecting terminal
Inventor: SEKIGUCHI TOSHIKAZU
IPC: H01M2/20
Filed: 1989-09-07
Abstract: PURPOSE:To maintain a stable connection over a long period by providing plural conductive plate spring pieces with respective conductive connecting pins to be disposed in respective positions different in distance from a base portion, the plural conductive pieces being in conduction to each other by the above base portion. CONSTITUTION:In a battery connecting terminal 1, conductive plate spring pieces 2a, 2b and conductive connecting pins 4a, 4b are both in conduction to each other by the base portion 2 of the spring pieces 2a, 2b, and therefore function as common terminal assembly electrodes for a battery electrode 6. The terminal 1 performs electrical connection to the battery 6 when its two pins 4a, 4b have their ends made to abut on different positions of the battery 6 with different elastic pressing forces. Since the pins 4a, 4b have their ends made to abut on different positions of the battery 6 with different elastic pressing forces independent of each other, the terminal 1 is stably held in contact with the above electrode 6.

Title: Measuring device of viscosity of high-temperature melt
Inventor: SHIMIZU KOUJI
IPC: G01N11/06
Filed: 1982-12-23
Abstract: PURPOSE:To measure safely and easily the viscosity of a high-temp. melt by providing a capillary outflow pipe at the bottom of a sample container made of aluminum, hanging the container on a weight measuring device by using a suspension wire, and measuring the sample viscosity by the weight variations per hour of the sample flowout quantity from the outflow pipe. CONSTITUTION:A sample container 4 made of aluminum providing a capillary outflow pipe 7 at the bottom is hung on a weight measuring device 10 on a stand 1 by a platinum heat resistant and anticorrosive wire 9 which hangs the holes 8, 8 around the periphery of the upper mouth of the container 6 and put in a measuring pipe 3 surronded by an electric furnace 2. A thermocouple 12 is inserted into the measuring pipe 3 and the weight variation and the temp. at the time when the sample in the container 6 flows out are recorded on a recorder 11. The weight variation per hour of the sample is obtained and the viscosity is calculated by an analytical curve made by the sample whose viscosity is previously known. Thus, a low-melting point alloy is not made from the sample containing heavy metals such as Sn, Pb like the ash generated from an electric dust collector and the viscosity measurement can be carried out in an atmosphere generating a harmful gas such as SOx, HCl.

IPC: C30B29/16
Filed: 1998-08-17
Abstract: PROBLEM TO BE SOLVED: To perform the epitaxial growth of a metal oxide membrane easily by a simple apparatus by depositing the membrane on the surface of a substrate by the oxidation-reduction reaction between electrons and positive holes generated on the surface of the substrate and metal ions and an oxidizing agent. SOLUTION: For example, a titanium dioxide single crystal substrate 2 to form a metal oxide membrane is arranged in a reactor 1. The surface to form the membrane of the substrate 2 is made to be a polished (100) surface. The reactor 1 has a window 3 made of an optically transparent material, light beams are radiated through the window 3. When the light beams are incident on the substrate 2, pairs of an electron and a positive hole are generated on the surface of the substrate 2, the produced electrons reduce an oxidizing agent, and simultaneously the positive holes oxidize Pb2+ ions so that a thin PbO2 membrane is deposited on a metal surface by the electric reaction between the surface of the substrate and the metal ions and the oxidizing agent.  Electroless oxidation proceeds with the deposited thin PbO2, membrane acting as forming nuclei, and a PbO2 membrane having a desired thickness can be formed.

Title: Vertical magnetic head device and its production
Inventor: MURATA AKIHIRO
IPC: G11B5/127
Filed: 1983-12-07
Abstract: PURPOSE:To enable mass production of vertical magnetic head devices with simplification of the device constitution by forming a projection part on a substrate to secure a space between magnetic poles on a head surface for an end face together with a thin film magnetic pole part to form a magnetic pole end face on the head surface and opposite to said projection part and a conductor coil part which crosses said thin film magnetic pole part. CONSTITUTION:A recording medium 1 contains an upper layer of a hard vertically magnetized film 2 made of Co-Cr, etc. and a lower layer of a soft intra-face vertically magnetized film 3 of ''Permalloy'', etc. Then the medium 1 is revolved toward an arrow A and against the surface 47 of a magnetic head. In a data recording mode a prescribed current if flowed to an energizing coil 45 to energize magnetic poles 42 and 43. A magnetic flux 48 close to an end face 44 produces an intensive vertical magnetic field at a part right under a main magnetic pole 42 having small width. Then the film 2 is magnetized toward the magnetic field. Thus data are recorded. In a data reproduction mode the induction voltage produced at both ends of the coil 45 by a change of the magnetic flux inside the pole 42 when the magnetization inverted part of the film 2 passes through the pole 42 is used as reproduction signals. In such a way, the number of manufacturing processes is greatly reduced owing to the coil part formed at the side of the head surface.

Title: Automatic voltage adjusting device
Inventor: TAKAGI KOZO
IPC: H02P9/10
Filed: 1998-08-18
Abstract: PROBLEM TO BE SOLVED: To prevent the overvoltage of a generator output voltage by obtaining a deviation signal between the maximum phase voltage of a maximum value in the three phase output voltages of a generator and the target value of a voltage setting unit in a comparator and adjusting the field voltage of the generator in an exciting device, based on the obtained deviation signal. SOLUTION: Three-phase voltage detectors 14 are installed in a maximum phase voltage detector 13. The phase voltage detectors 14 detect the valid values of the respective phase output voltage of a generator. A maximum value detection circuit 15 selects the maximum value of the detected output phase voltages and is outputted to a comparator 16. The comparator 16 calculates the deviation signal between the phase voltage of the selected maximum value and the target value of a voltage setting unit 7. An excitation control circuit 8 outputs a control command for adjusting the field voltage of the generator to an exciting device, based on the calculated deviation signal. Thus, the output voltage of the generator can be controlled at all times in such a way that it does not become overvoltage.
